Estratégia RSI Donchian
A estratégia RSI Donchian busca extremos de momentum que coincidam com rompimentos do Canal Donchian. O índice de força relativa mede condições de sobrecompra e sobrevenda enquanto o canal define os máximos e mínimos recentes de preço.
Os testes indicam um retorno anual médio de aproximadamente 82%. Funciona melhor no mercado de ações.
Um sinal de compra aparece quando o RSI está acima de RsiOverbought enquanto o preço rompe acima da banda superior do Donchian. Um sinal de venda se forma quando o RSI está abaixo de RsiOversold enquanto o preço cai pela banda inferior. As saídas ocorrem assim que o preço retorna à linha média do Donchian, sinalizando um retorno ao equilíbrio.
Este método funciona bem para traders ativos que preferem seguir um momentum forte, mas ainda negociam com níveis claros de rompimento. O stop-loss ajuda a limitar o risco se o momentum não reverter rapidamente.
Detalhes
- Critérios de entrada:
- Comprado: RSI > RsiOverbought && Close > Donchian High
- Vendido: RSI < RsiOversold && Close < Donchian Low
- Comprado/Vendido: Ambos os lados.
- Critérios de saída:
- Comprado: Sair quando close < Donchian Middle
- Vendido: Sair quando close > Donchian Middle
- Stops: Sim, stop-loss percentual.
- Valores padrão:
RsiPeriod = 14
DonchianPeriod = 20
RsiOverbought = 70
RsiOversold = 30
StopLossPercent = 2
O canal é a máxima e a mínima dos DonchianPeriod candles anteriores, e o seu meio fica a meio caminho entre elas. Um rompimento de alta é confirmado quando o RSI está acima de RsiOverbought e um de baixa quando está abaixo de RsiOversold; a leitura oposta, um RSI sobrevendido num fechamento acima do canal, praticamente não ocorre. O stop é um StopLossPercent fixo do preço de entrada, vigiado também entre os candles. Um sinal de entrada contra uma posição aberta a inverte.
